staging: android: ion: Clean unused debug_show memeber of the heap object
ION had supported heap debug info under /sys/kernel/debug/ion/<heap_name>.
This support have been removed but some leftovers (dead code) still exist.
This patch removes the existing dead code.
Fixes: 15c6098cfec5 ("staging: android: ion: Remove ion_handle and ion_client")
